Results and Conclusions:
The heat test was successful for both parts. The UPT-SM5/200, a 5kW power supply, was able to heat both parts to over 1400F (760C). The heat time on the 1” (25.4mm) tip can be slightly improved upon by increasing the transformer ratio which will allow the unit to get full 5kW power instead of 4.5kW.
The 0.265” (6.73mm) OD tip can be heated at a much faster rate if the unit is retuned. If you are using a coil specific to this part with the full 5kW output of the system, a heat time of 2-3 seconds can be achieved. At the current settings, the unit only ran at half of its power limit (2.5kW). The heat time can be improved upon even further by changing the coil design to adjust it to the smaller part.
Temperature readings were taken with a Williamson dual wavelength IR system.
